Bear in mind oigle is based in Australia according to his profile.
True but that oil is perhaps even more suitable in British climate than in Oz due to its low cold viscosity. I used 15W/40 Shell Rimula mineral diesel oil for years with great results. It is easy to overkill with oils. The OP did ask for the "best" and I believe that the Shell product mentioned is up there with the best. The biggest benefit with 5W/40, as I see it, is the ability to circulate through your motor very quickly on cold start - the known proven time when 90% of engine wear occurs.
